To all whom t may concern,.- u

Beit known that we, FRANK Pit-ROY Brunn, residing at 181 Union Street,Southwark, and HENRY PETER CoLLrvnn, residing at 73 Grot ton Road,Oamberwell, London, England, sub= j eots of the Queen of Great Britain,have invented certain new and useful Improvements in Spring-Hinges,(patented in Great Britain, No. 22,320, datedNovember 22,l895,) of whichthe following is a specification.

This invention relates to a hinge and spring combined for use with seatsof sanitary and other closets, to doors, easements, and windovv-sashesgenerally to lift or open same and retain them lifted or open exceptwhen pressure is applied to fold down or to close them.

The invention consists of a spring inclosed in a barrel projecting fromone flap of a hinge, said spring being adjustable as to power by an endplug which can be screwed more or less into the barrel, a movableGupshaped follower being within the barrel and bearing against thespring to localize its central thrust and reduce friction, a quadrantpin being jointed to the cap and to the opposite flap or hinge, bothnaps moving on a pintle, as with butt-hinges.

The invention is represented on the annexed i drawings.

Figure l is a face view of hinge with one iiap open and showing thepinjointed quadrant-bar partly in the hole leading to the spring; Fig.2, asectional elevation of barrel with opposite hinge-flap open 5 Fig.3, a parts'ectional elevation of barrel With opposite hinge-flap closed;Fig. Il, a sectional elevation of closet-seat raised by the spring inbarrel, this being in position in back rest for the purpose.

In order to enable those skilled in the art to make and use ourinvention, we will nonr describe the same in detail, referring to thedrawings, wherein the letter A indicates aspiral spring, B a cupshapedfollower, and C a short lug.

D indicates a segmental link pivoted to lug C at one end and at theother to lug E, projectin g from inner face of half-iiap F of hinge, theadjoining half G being formed With a hole H for the free passage of thequadrant D when the hinge is closed by hand to compress the spring A,the expansion of the spring A when the hinge is free being to open theseat I or the door or Window, as the case may be, and to which theinvention is fitted.

J is a barrel containing spring A, the tension on said spring beinggoverned by the distance the screw-plug K is screwed in.

The invention is specially suitable for those closets in which the panis used as a urinal and for reception of houseslops when the seat israised, and which by the present invention is automatically lifted andretained until depressed for the usual use of the pan for personalpurposes.

Vhat We claim, and desire to secure by Let- The combination in aspring-hinge, of two hingeA iiaps or leaves, a barrel having an inclosedspring, a follower arranged in the barrel and pressed outwardly by thespring, and a segmental link pivoted at one end to the follower and atthe other end to one of the hinge iiaps or leaves, substantially as andfor the purposes described.

In testimony whereof We have hereunto set our hands in presence of twosubscribing Witnessess FRANK PERCY RDER. HENRY PETER COLLIVER.
